Choose the best answer 1. As filtrate moves through the mammals, it generally undergoes a dramatic decrease in osmolarity. A. Distal convoluted tubule B. Bowman's capsule C) Descending segment of the loop of Henle D. Proximal convoluted tubule E. Ascending segment of the loop of Henle 2. If a person is taking a drug that completely inhibits angiotensin-converting enzyme (ACE), what will happen to aldosterone secretion when the person goes on a low sodium diet? A. There would likely be no increase in aldosterone production B. There would be an increase in production of angiotensinogen from the kidney C. Aldosterone production would increase, resulting in high blood pressure . D. The adrenal medulla would decrease its production of aldosterone E. There would be an increase in production of ADH from the anterior pituitary gland 3. Creatinine is a waste product from the normal breakdown of muscle tissue. As creatinine is produced, it is filtered through the kidneys and excreted in urine. Doctors measure the blood creatinine level as a test of kidney function. The kidneys filter creatinine from the blood into the urine, and reabsorb almost none of it. The amount of blood the kidneys can make creatinine-free, each minute, is called the creatinine clearance. Creatinine clearance in a healthy young person is about 125 milliliters per minute- meaning each minute, that person's kidneys clear 125 ml of blood free of creatinine. The creatinine clearance is a good estimation of the A. counter-current multiplier system B. RAAS system C. kidney's ability to regulate phH D. kidney's ability to adjust water loss E. glomerular filtration rate 4. Juxtaglomerular cell tumor (JCT) is an extremely rare kidney tumor of the juxtaglomerular cells that typically secretes renin. A person with JCT is likely to develop_ A. severe hypotension B. Grave's Disease C, severe hypertension D. Type 1 diabetes E. Cushing's Disease 5. Furosemide (also called Lasix) is a loop diuretic that may be used to treat hypertension (high blood pressure) and edema (fluid accumulation/swelling). How might furosemide work in the body? A. It could act on the Na+/K+/2CI- symporter (NKCC2) in the thick ascending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption. 8. It could act on the Na+/K+/2C symporter (NKCC2) in the descending limb of the loop of Henle to inhibit sodium, chloride and potassium reabsorption. C. It could act on the Na+/K+/2CI- symporter (NKCC2) in the descending limb of the loop of Henle to increase sodium, chloride and potassium reabsorption. D. It could act to decrease the glomerular filtration rate (GFR), which would increase the production of urine E. It could inhibit ANP, which would lower one's blood pressure
